    wiring a LED lit rocker switch

    . Sir Roadcase . . . . . This one's gotta work for you, as it additionally explains the hidden electro-mechanics within the switch. Rocking the switch on gives power to your controller as well as power to the series current limiting resistor and the LED and then they complete their power...

    Neon lamp for turntable repair

    . Sir Foghorns . . . . . . . Possibly . . . . Looks like this might be the definitive replacement for that lamp. Note that the electrodes are designed for a spot production of illumination, then the lens built into the end of the envelope , provides for even further spot concentration. It...

    How to ground unwanted AC from a metal case?

    . Sir Mikael Lavoie. . . . . . . " i found that there is a 3,2V AC current coming from the case (stainless steel case). I removed the mounting and put a layer of rubber behind it and mounted it with plastic bolt to isolate it from the machine. But i still have a 2.4V AC coming from the...

    Help with Power supply to Florescent display circuit fault

    . Sir Jimkarl . . . . . . . You had broken a lead totally off from a regulator xstr. And that was probably because that odd transistor is like a TO-92 but has a 3/8 width of 1/8th of an inch thick . . . . . . . . .repeat . . . . . 1/8th of an inch thick aluminum conforming heat sink formed...

    Amplifier blows power fuse

    .. TWITMAC : Effective as of post # 27 . . . . . "So this project has unfortunately fizzled out - the owner of the amp decided it was not worth paying anything to have it repaired (I guess he got an idea of the extent of the damage) and elected to replace it with a new unit. Equally...

    Diode identification help

    Sir Steve Goldson . . . . . . . That's a current spec that your application will not see, so disregard. A 1N4937 or UF4007 diode would be fine for your replacement. Also I would like to have a camera view of the semis mounted on that major silver heatsink. or a read back. If neither of ...

    Components for small peristaltic pump

    . Sir John Rock. . . . . . . I can see your power supply as being fully adequate. Now I'm just fully trying to digest the max 5000 rpm spec on the universal motor. And I don't quite think that I see a gear case spaced in there between the motor shaft and drive roller. I'm used to seeing...
